Title: Backrest assembly for a wheelchair
Inventor: BAR CHRISTOPHER
IPC: A61G5/12
Filed: 1992-02-18
Abstract: A contoured backrest (24) for a wheelchair (A) may be moved to and retained in different positions and thus accommodates individuals of varying size and disabilities. The backrest (24) carries clamps (52, 70) to which outriggers (40, 42) are fitted, and these outriggers (40, 42) extend transversely across the back face of the backrest (24). The outriggers (40, 42) are laterally adjustable to accommodate wheelchairs of different widths. They have offset ends (54, 56) beyond the sides of the backrest (24), and these ends (54, 56) fit into brackets (44, 46) on back posts (16) that are part of the wheelchair (A). When the clamps (52, 70) are released, the outriggers (40, 42) may be rotated. This enables the positon of the backrest (24) to be adjusted forwardly and backwardly, upwardly and downwardly, and angularly.
Patent CA-2082025-A1 (CA)
Inventor: RUSH JONATHAN E
IPC: B65D47/36
Filed: 1992-11-03
Abstract: A disposable cup lid has intersecting straw insertion slits and rip-stop end cuts located transversely to and spaced from the ends of the straw insertion slits.  In a preferred embodiment, the rip-stop end cuts are stamped lines of weakness or perforations, located perpendicularly to, and between about 1/32 and 1/16 inch beyond, the ends of the straw insertion slits.  In another preferred embodiment, the end cuts are portions of the arc of a circle with a diameter slightly larger than the length of the straw insertion slits.  The rip-stop end cuts, together with the straw insertion slits, define frangible reinforcing webs connecting wedge-shaped lid portions defined by the straw insertion slits.  The webs strengthen the cup during shipment, during mounting on the cup, and during transportation of the filled cup prior to insertion of the straw.  The webs are broken by insertion of the straw, resulting in a structure that effectively prevents the force of straw insertion from tearing the top surface of the lid.

Title: Polymerization of vinyl chloride
Inventor: SEIICHI MASUKO
IPC: C08F2/00
Filed: 1990-12-28
Abstract: ABSTRACT  In a novel method of homo- or copolymerization of vinyl chloride, a specified coating agent is applied on the surfaces of the portions which will become into contact with the vinyl chloride monomer during the polymerization process. The coating agent is in a form of an aqueous solution of a modified condensation product of phenol and aldehyde, the pH of the solution being adjusted in a range that the product is dissolved at an ambient temperature upon coating of the solution and separates out of the solution upon being heated on the surfaces.  The wall surface of the polymerization tank and the like is then coated with a thin film of the coating agent having a uniform thickness and being strongly adhered to the wall surface, thereby providing an excellent effect of preventing adhesion of the product polymer to the wall surface.

Title: Staggered short pleat air filter
Inventor: ADAMS MICHAEL D
IPC: B01D29/21
Filed: 1994-02-09
Abstract: A high velocity air filter includes a hollow, generally cylindrical filter element comprised of a filtering material folded to extend back and forth between inner and outer peripheral surfaces to define a series of pleats extending longitudinally of the filter element.      The inner edge of a plurality of the pleats is a lesser distance from the longitudinal axis of the filter element than the inner edge of the other pleats, thereby forming a plurality of short pleats and a plurality of long pleats.      The inner diameter of the filter element is less crowded than in conventional high velocity air filters. The restriction to airflow is thus lowered without increasing the surface area of the filter media or sacrificing the capacity of the filter element.

Title: Anti-Fatigue Mat
Inventor: HOROWITZ ALLAN J
IPC: A47G27/02
Filed: 1994-04-11
Abstract: A mat adapted to relieve fatigue in a person standing on it without shoes or boots, and formed from fine cell foam having a density of between 1.5 and 2.5 pounds per cubic foot, with thickness between 0.75 and 1.5 inches, and a compression strength at 25% compression of between 10 and 17 p.s.i.  The mat has sloping edges and is covered by carpet.  When a person in bare or stocking feet stands on the mat, the mat partially compresses but has remaining resiliency such as to produce a swaying motion in the person.  This results in increased muscle action and blood circulation in the feet, legs and hips and some spinal movement, reducing fatigue.

Patent CA-2138512-A1 (CA)
Title: Air separation
Inventor: RATHBONE THOMAS
IPC: F25J3/04
Filed: 1994-12-19
Abstract: A stream of air is compressed in compressor 2 and has water vapour and carbon dioxide removed therefrom in purification unit 4. A part of the resulting purified air is cooled by passage through heat exchanger 6 and is employed to heat an intermediate reboiler 24 in a lower pressure rectification column 42. The air flow from the reboiler 24 passes into a higher pressure rectification column 20 which supplies a stream of oxygen-enriched liquid air for separation in the lower pressure rectification column 42. Liquid nitrogen reflux for the higher pressure column 20 is provided by taking nitrogen vapour from this column through outlet 30 and condensing it in another intermediate reboiler 32 located above the reboiler 24 in the rectification column 42. The condensed nitrogen is returned to the top of the column 20. Another air stream is employed to reboil a further reboiler 16 at the bottom of the lower pressure rectification column 42 with the resulting condensed air stream being introduced into the higher pressure rectification column 20 through an inlet 22. An impure oxygen product is withdrawn from the bottom of the lower pressure rectification column 42 through outlet 58 in liquid state and is vaporised in the heat exchanger 6. The arrangement of reboilers 16, 24 and 32 facilitates operation of the apparatus with a relatively low pressure ratio between the operating pressure of the column 20 and that of the column 42.
